Visa requirements
Whether you need a visa, and how to apply, depends on your citizenship and your situation. The authoritative sources are the U.S. Department of State’s visa pages and the U.S. embassy or consulate in your country. Citizens of Visa Waiver Program countries can check the Electronic System for Travel Authorization (ESTA) of U.S. Customs and Border Protection.
Visa appointment wait times vary by country and can be long, so start early. The organizers cannot advise on individual cases.
Invitation letters
The visa invitation letter request form will become available when conference registration opens. It will be posted on this page.
